SPECIFICATION forming part of Letters Patent No. 452,027', dated May 12,1891.

Application filed September 6, 1890. Serial No. 364,171. (No model.)

To all whom t may concern:

Be it known that I, AMBRosE S. VosE, a citizen of the United States, anda resident of East Boston, in the county of Suiolk and State ofMassachusetts, have invented certain new and useful Improvements inSole-Trimming Machines; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification.

My invention relates to improvements iu boot and shoe soletrimming-machines.

The object of the invention is to provide an adjustable shield orgagefor the revolving cutter of sole-trimming machines. As nowordinarily constructed such cutters are provided with annular shields orguides attached thereto, so as to revolve therewith. Such guides orshields, which are intended to run in the groove between the sole andthe upper of a shoe, are very objectionable, as they sometimes come incontact with the leather of the upper while revolving at a high speed,thereby injuring and damaging the same. In the usual construction alsoit is extremely difcult to remove the` knives of the cutters for thepurpose of grinding or sharpening, and they otherwise possess seriousdefects and disadvantages.

In my invention the guide or shield is mounted upon a shaft in line withbut separate from the cutter, so that while the said shield may bereadily rotated, if desired, by the shoe-sole, which is in contacttherewith, it has no connection with the cutter and does not revolvetherewith, so that there is no danger of injuring the upper. The shaftcarrying the said shield is also adjustable in a pivoted frame, whichmay be swung upout of the way, so that the knives can be removed fromthe .cutter Without taking the latter out of the machine. The guide canalso be adjusted longitudinally, so as to bring it nearer to or fartherfrom the cutter, according to the thickness of the sole being operatedupon.

The invention consists in the novel construction and combination ofparts hereinafter fully described, and definitely pointed out in theclaims.

In the accompanying drawings, Figure 1 is a side elevation of asole-trim ming machine constructed in accordance 'with my invention.

Fig. 2 is a sectional viewof a portion of said machine, showing thepivoted frame and the adjustable shaft carrying the shield or guide.

In the said drawings, the reference-numeral 1 designates the bed or baseof the machine, adapted to be secured to any suitable support andprovided with bearings 2 2, in which is journaled the main drivingshaft3, which carries the revolving cutter 4. The bearings 2 2 are providedwith the usual lubricators 5, and the shaft has a driving-pulley 6. Thecutter 4 may be of any ordinary or suitable construction, and issecurely fixed or secured to said shaft, so as to revolve therewith.Underneath the cutter is a Wheel 7, pivoted in an arm 8, secured to andprojecting from the bed 1. The bottom of the shoe-sole rests against thewheel while the sole is beingl trimmed.

The numeral 9 designates an arm projecting upwardly above and in frontof the cutter, and at its free end is bifurcated, forming two arms 10.Through these arms pass two set-screws 12, which engage with and formpivoted bearings for a sleeve 13, so that the latter is capable ofoscillating thereon. This sleeve carries a vertical bar 14, the upperend of which is provided with an annular groove 16, with which engagesa` set-screw 15, projecting through a plate 18, secured to the upper endof sleeve 13. The sleeve lis also provided with a screw-threaded recessat its lower end, in which is also a set-screw 19, the end of whichengages with the bar 14 and holds it in place. To the lower end of thebar 14 is secured a plate 20, having downwardly-depending ilanges 21 ateach side, forming ways for the sliding carriage 22, provided Withdownwardly-depending boxes 23, in which is journaled the shaft 24,carrying at its inner end the annular shield or guide 25.

The carriage 22 is provided with a longitudinal screw-threaded recess,in which works a correspondingly-threadedscrew-rod 26, provided With amilled head 27. This rod also passes under a plate 28 on the outer endof the plate 20. This plate has downwardly-proj ecting semicircularflange 29, which engages between twoannular flanges on the screwrod,and

thus prevents any horizontal or longitudinal movement thereof, butpermits it to be rotated by means of the milled head. The shaft 24 andthe shield which is secured thereto are capable ot' being rotated, andthe shield is provided upon its face with recesses to receive the end ofthe projecting portions of the cutter, which fits snugly but loosely insaid recesses. The shaft 24Cis prevented from longitudinal movement bymeans of the collars 30, fixed thereon.

Upon the upper side of the arm 9 is a pivoted lever 3l, one end of whichis adapted to engage with the pivoted sleeve 13 and prevent it fromoscillating. The other end of the lever forms an operating-handle.

Secured to the under side of arm 9 are adjusting-screws 32, which lnaybe employed to regulate the distance of the plate carrying the shieldand its connections from the cutter.

The operation is as follows: The sleeve being operated upon is held withthe bottom of the sole against the wheel 7 and the shield or guidebetween the upper and sole. As the driving-shaft revolves it revolvesthe cutter without, however, rotating the guide or shield, therebypreventing any liability of injuring the upper. Theshield is verticallyandlongitudinally adjustable by the means described, and when it isdesired to remove the knives from the cutters the frame carrying theshield and its connections can be swung entirely out of the way, thepivoted sleeve 13, carrying the sant e, turning upon the pivots l2.

Having thus described my invention, what I claim isl. In a sole-trimmingmachine, the combi nation, with the bed, a driving-shaft, and a rotating cutter secured to said shaft, of an arm secured to said bed andprojecting upwardly and in front of the cutter, a sleeve pivotedin saidarm, a rod vertically movable in saidJ sleeve, a retaining-screw passingthrough said sleeve and engaging with the rod, a plate secured to thelower end of said bar, having downwardly-depending flanges forming waysor guides, a sliding carriage engaging with said ways and having ascrew-threaded recess to receive a correspondiu gl y-threaded adj ustingrod, a shaft carried by said carriage, and a shield or guide secured tosaid shaft, substantially as described.

2. In a sole-trimming machine, the combination, with the bed, thedriving-shaft, the cutter secured to said shaft, and the wheel locatedunderneath the cutter, of the bifurcated arm secured to said bed andprojecting above and in front of the cutter, the set-screw passingthrough the bifurcations, the sleeve Apivoted on said screws and havinga retainingscrew near its lower end, the vertically-movable bar workingin said sleeve and provided with an adj usting-screw, the plate securedto the lower end of said bar, having depending danges forming ways orguides, the carriage sliding on said ways and provided with ascrew-threaded adjusting-rod, the boxes depending from said oarriage,1heshaft journaied therein, the shield or guide carried by said shaft,theadj usting-screws carried by an arm secured to the lower side of thearm se# cured to the bed, and a lever pivoted to the upper side of saidlast-mentioned arm, substantially as described.

In testimony that l claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
